	 * Simple-addres  地址联动组件
	 * @description 三级地址联动，支持（app）nvue、小程序、H5
	 * @tutorial https://ext.dcloud.net.cn/plugin?id=1084
	 * @property {String} animation 是否开启动画
	 * @property {String} type = [bottom] 弹出层类型，暂时只支持底部弹出
	 * @property {Boolean} maskClick = [true | false] 是否允许点击遮罩层关闭
	 * @property {Boolean} show = [true | false]  显示或隐藏地址组件
	 * @property {String} maskBgColor 遮罩层背景颜色
	 * @property {String} cancelColor 取消按钮颜色，默认为：#1aad19
	 * @property {String} confirmColor 确认按钮颜色，默认为：themeColor
	 * @property {String} themeColor 主题颜色，后续会废弃该配置，建议使用`cancelColor`或`confirmColor`
	 * @property {String} btnFontSize 取消、确认按钮字体大小，默认为`uni.scss里的 $uni-font-size-base `
	 * @property {String} fontSize picker-item字体大小，默认为：28rpx
	 * @property {Array} pickerValueDefault 默认值，可以通过function queryIndex 获取
	 * @property {Function} queryIndex 根据自定义信息返回对应的index
	 * @property {Function} open 打开
	 * @example  <simple-address ref="simpleAddress" :pickerValueDefault="cityPickerValueDefault" @onConfirm="onConfirm" themeColor='#007AFF'></simple-address>
